Description

The Scorpion S-40mm series of motors are built with 6mm hardened steel shafts that will last through countless hours of flying fun, but occasionally, on a "Less than Perfect" landing, you may bend or break one. For these occasions, we offer factory replacement shafts for all the S-40mm Scorpion Motors. Our Motor Shaft Kits include an original equipment factory shaft with the setscrew key-ways already cut, a new shaft retaining collar, and a replacement setscrew for the retaining collar.

The shaft for the S-4025 series airplane motors measures 6mm in diameter, and is 83.5mm long. The shaft kit will also fit other brushless motors that require a 6mm shaft of this length. The shafts can be cut shorter with a Dremel tool and a cut-off wheel if necessary to fit other motors.

Note: the shafts in the Scorpion motors are a slight press fit into the aluminum front housing. The shafts will not just slide out when the setscrews are removed. They need to be pressed out in a bearing press, or in a drill press, with the front housing of the motor supported in a block of wood to prevent warping the front housing. Never tap the shaft out with a hammer. The shock induced can bend the motor parts and knock the glue joints loose on the motor magnets.
